Definitions
- the invention relates to a method and a casting / rolling plant for producing hot-rolled metal, in particular high-surface-area steel strip from slab or flat cast thin-cast slabs cast in the continuous casting process, which descaled on its strand surface. pe.atur heated and finished in a multi-stand hot strip rolling mill with low strip thicknesses, the cast strand after emerging from a strand guide, before entering a heat balance furnace and / or after exiting a heat equalization furnace and entering the hot 0, strip rolling mill on one or both strand surfaces by a plurality of rotating nozzles, from which pressure liquid injected repeatedly to a respective same surface location with high loading pressure, freed of scale and / or casting powder and the oscillation marks are deeply cleaned.
- a descaling device for casting and rolling mills is known.
- a rotatable arm is used with nozzle and retention, protection and recovery plates for the removed scale and the large amount of spray water proposed.
- a first descaling device is known, which may consist of a scale washer of conventional design and a second descaling device with rotating nozzles.
- the invention has for its object, in addition to the application of the rotating Entzunderns previously included not included parameters that are given by the continuous casting.
- the stated object is achieved according to the invention in combination with the genus specified in the introduction by driving the hydraulically oscillated continuous casting mold in several different oscillation curves and by performing the deep cleaning of the oscillation marks by setting the oscillation profile determined as optimal for each casting material.
- the advantages are that in addition to the actual descaling now the oscillation marks can be cleaned very largely and thus a finish rolling on ultrathin Endwalzdicken equal / smaller 1, 2 mm is favored. This means that, for example, for these dimensions, finish rolling in the austenite region of the crystal structure is possible.
- the pressurization of the rotating nozzles with printing fluid by significantly less pressure medium than hitherto has been used in so-called.
- Tinder scrubbers with the same parameters of the casting or rolling process.
- printing medium such as, for example, water
- the associated casting-rolling plant in particular a compact-casting-rolling plant (CSP), consisting of a continuous casting for liquid metals, in particular for liquid steel materials
- the continuous casting mold is connected to a hydraulic oscillation drive, in the strand discharge at least a strand guide, a temperature compensation furnace, possibly a furnace ferry and a multi-stand hot strip finishing train and a reel follow, is further developed such that between the strand guide and the temperature compensation furnace or between a straightening and scissors and / or between the temperature compensation furnace and de warming belt finishing mill a device is arranged with rotating nozzles, from which a pressure medium with high applied pressure is repeatedly directed to a respective same surface location.
- a plurality of nozzles for pressure medium are arranged on a rotor.
- Another embodiment provides that a plurality of rotors are arranged with arranged on the rotor circumference nozzles for pressure medium in a row transverse to the course of the casting or rolling train.
- the previously used Abspritzbalken the scale scrubber can be replaced individually or completely.
- the use of rotor descaling on a hot strip rolling mill having seven or more finishing stands is provided prior to entry into the first finish rolling mill.
- Fig. 1 is a casting-rolling compact plant in a perspective side view
- Fig. 2 is located in a compact protective housing continuous casting mold with hydraulic oscillation drive
- FIG. 3 shows several diagrams of different oscillatory movements of the continuous casting mold and FIG. 4 shows a single rotor with nozzles arranged on the rotor circumference.
- a casting / rolling plant 1 which in particular represents a CSP plant (Compact Steel Plant), consists of a continuous casting apparatus 2, in which liquid metal, in particular liquid steel material, is cast by means of a continuous casting mold 9.
- the continuous casting mold 9 is provided with a hydraulically oscillating drive 9a (FIG. 2).
- On the continuous casting mold 9 follows in strand withdrawal direction 11, a strand guide 3, a temperature compensation furnace 4, if provided, a furnace ferry 5 and a multi-stand hot strip finishing train 6 and behind a reel 8 for winding the tape. 7
- a device 14 with rotating nozzles 15 (FIG. 4) is arranged, from which pressure media (usually liquid, such as, for example, water) is repeatedly directed to a respective same surface area with a high pressure.
- pressure media usually liquid, such as, for example, water
- FIG. 3 the hydraulically oscillating continuous casting mold 9 is moved in a plurality of different oscillation curves 16, 17, 18, so that a respectively different oscillation profile 16a, 17a, 18a is produced for the respectively selected casting material.
- the oscillation curves 16, 17, 18 can be due to different Kokillenhübe, different casting speed, unleading leading mold speeds on the downstroke (so-called negative strip) different waveforms (eg, sinusoids) u. Like. Be obtained.
- the pressurization of the rotating nozzles 15 with hydraulic fluid 19 can be done with significantly less pressure medium (pressure medium) than has been used in so-called. Zundericaschern, where equal ratios, ie parameters of the opposing processes are based.
- pressurizing the rotary nozzles 15 with pressure medium keeps the temperature losses of the casting strand 2b as low as possible.
- a plurality of nozzles 15 for the printing medium are combined on a rotor 20 (FIG. 4) and a plurality of rotors 20 have nozzles 15 for printing medium mounted on the rotor periphery 20a and are arranged in a row of nozzles 21 transversely to the course of the casting or rolling train 2b arranged. Advantages also result from a plurality of such rows of nozzles 21, smaller nozzle jets than can be used in a single row of nozzles 21.
- the rotor descaling may be applied to a hot strip rolling mill 6 having seven or more finish rolling stands 6a prior to the entry of the rolled strip into the first finish rolling stand 6a.
